ghosted - Computer Definition

(1) Being ignored in a social environment. In today's world of electronic socialization, it is very easy to not respond to a friend's e-mail, text message, chat request or other form of communication.

(2) The grey or fuzzy appearance of menu text or toolbar buttons, which indicates that the operation is not currently selectable. Ghosted designs were popular in the early days of personal computing when software emulated manual methods. In the 21st century, a flat appearance became fashionable. See iOS 7 and Material Design.
